One problem related to tire tread/belt has been reported for the 2020 Tesla Model X. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2020 Tesla Model X based on all problems reported for the 2020 Model X.
Both rear tires (original tires) on the vehicle had broken belts at about the same time. My understanding is that broken belts can lead to tire failure which can pose a significant safety risk. Our local Tesla dealer diagnosed the problem, and the tires have been sent to the tire manufacturer for their own inspection. There were no warnings. Tire size: 275/45 r20.
